The only coins I can find attributed to Bela are the falus of Mir Jamir Khan (1830-1869) like this:

At 5-6 grams, this coin appears to be the adelho (½ pice) being referred to in the article.
Today we appear to have this coin listed as Khanate of Kalat:
N#492208
When I search for Kalat on acsearch, I find only copper coins struck under Nawaz Khan (1839-41) or Khudadad Khan (1856-93)
So, I will create Bela with ruling authority for Mir Jamir, then move the coin. I will also add two ruling authorities for Kalat.
